Overview

Registered in 2006 as a sport of *Hosta* 'Edge of Night', 'Ice Castle' is a medium-sized cultivar distinguished by its blue-green leaves with wide creamy white margins. A notable feature is the lighter green area that appears where the white margin overlaps with the darker green center, creating a subtle tri-color effect on the broadly ovate, lightly corrugated foliage.

In the Garden

'Ice Castle' forms an upright, slow-growing clump reaching 18 inches (45.7 cm) in height and 32 inches (81.3 cm) in diameter. It performs best in partial to full shade, where the blue-green leaf centers retain their glaucous bloom. The pure white scapes, rising 15 to 17 inches (38 to 43 cm) above the foliage, provide contrast against the dark leaves. This medium-sized hosta pairs well with ferns, astilbes, and other shade perennials in woodland borders or foundation plantings.

Care Notes

Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Like most hostas, 'Ice Castle' is susceptible to slug damage and deer browsing in typical hosta-growing zones.
